To all whom t ma@ concern.'

Be it known that I, OTTO B. KIBELE, a citizen of the United States, residing atLos Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Removable Deep- Tell Pumps, of which the following is a specification.

My invention relates to newfand useful improvements in pumps for deep wells, the principal objects of my invention being to gene ally.' improve upon and simplify the construction of the existing types of deep well pumps, to provide a relatively simple andeliicient pump that comprises a minimum number of parts and which may be readily removed from the well without disturbing any part of the well tubing.

Further objects of my inventionare to provide an improved form of coupling for the well tube sections, which coupling is specially formed in order to receive a main cylinder or barrel of my improved pump, to provide relatively simple means for effectively packing the joint between the pump cylinder or barrel and the plunger that operates therein, to provide gravity means for retaining the-packing in proper position within the pump cylinder, and, further, to provide a deep well pump that is capable of being easily and cheaply` produced, readily assembled' or taken apart and which will be very eii'ective in performing its intended functions.

With the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement of parts that will be hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which:

Fig. 1 is avertical section taken lengthwise through the center of a deep well pump of my improved construction. V

Fig. 2 is a vertical section taken lengthwise through the center of the adjacent ends of a pair of well tube sections, and showing said tube sections connected by acoupling of my improved construction and which is designed to rece-ive the improved pump.

Referring by numerals to the accompanying drawings, which illustrate a practical embodiment of my invention, --10 designate the adjacent end portions of a pair of Well tube sections, the ends thereof being externally threaded, and seated on said threaded ends are the internally threaded ends of a coupling member 11, the same being tubular in form and provided with a relatively heavy wall between its threaded end portions.

Formed integral with the lower portion of the body of the coupling and immediately above theI lower internally threaded end portion, isan inwardly projecting flange 12 the upper face of which is inclined and finished to form a shoulder or seat 13 for the cylinder or barrel of my improved pump. The provision of the flange 13 forms a circular opening 14 in the lower portion of the coupling that is substantially smaller in diameter than the cylindrical opening 15 in the upper portion thereof.

My improved pump includes an elongated hollow cylindrical member 16, the external diameter of which is such that it will slide freelythrough opening 14. in the lower portion of the coupling 11, and the upper portion of said cylindrical body is enlarged as designated by 17 in order to fit snugly Within the larger chamber 15 in the upper portion of the coupling.

4The shoulder 18 between the main body portion of the cylindrical barrel 16 and the enlarged upper portion 17, is beveled and finished so as to co-operate with the finished surface 13 in producing a ground joint between the inclined or beveled joints when the barrel is properly positioned within the coupling.

The lower end of the pump cylinder or barrel 16 is provided with a suitable upwardly opening check valve, preferably of the type employing a ball 19 that normally rests on a suitably formed seat 20 and the movement of said ball away from its seat being limited by a suitable sto-p or cage 21.

Formed withln the pump barrel or cylinder 16 and at a point near its' upper end, is an internally arranged shoulder 22,,and the opening through said cylinder is enlarged at the upper end thereof to form a chamber 23 that is occupied by suitable packing 24, preferably a series of metal rings arranged in superimposed relation.

Bearing on Ithe upper end of this packing is the lower end of a hollow cylindrical member that is concentrically arranged within the well tube 10 that is connected to carries a. spider 26 which is effective in retaining said tubular member in concentric position within the Well tubing.

The weight of tube 25 causes it to perform the functions of Va gravity member in retaining the metallic packing 2,4 in proper position within the chamber 23 and against the plunger of the pump, which reciprocates through said packing, and in order to permit the free passage of liquid from the chamber within the lower portion ofl said gravity member into the chamber between said member and the well Ytube above the coupling 11, the lower portion ofthe wall of said member 25 is provided with suitable apertures 27.

Arranged for reciprocating movement through the metallic packing 24 and through the upper portion `of the pump cylinder or barrel 16, is the pump plunger 28, the same being tubular in form and provided on its external surface, adjacent to its lower end, with ashoulder 29 that is adapted to engage against shoulder 22 on the pump cylinder when the pump is lifted from the well tube.

The upper end of the plunger 28 is detachably connected in any suitable manner to the lower end of a coupling member30, and the upper end of the latter is detachably connected in any suitable manner to the lower end of a sucker rod 3l.

Arranged between the upper end of the plunger 28 and the intermediate portion of ,the coupling 30, is a suitable upwardly opening check valve, preferably of the type employing a ball 32 that normally rests on a seat 33 that is formed on the upper end of the plunger and the movement of said ball away from its seat being limited by a part of the coupling 30.

`During thel operation of my improved pump, valve 32 will be unseated on the downward movement of plunger 28, thereby permitting liquid to pass upwardly through said plunger, and said. liquid will flow past open check valve 32, from thence upwardly through gravity member 25 and out through the openings 27 therein.

Upon the upward movement of plunger 28, check valve 32 will close, and check valve 19 at the lower end of the pump barrel or cylinder 16'will be drawn open by the suction produced by the upward movement of the pump cylinder, and liquid will be drawn into the chamber -within the lower portion of said cylinder or barrel 16 past said open check valve 19. When it is desired to remove the pump from the well tubing it is only necessary to lift the sucker rod 31 until the shoulder 29 on the plunger 28 engages against shoulder 22 on the barrel 16, and as a result of such engagement, said barrel will be lifted and drawn upwardly with the sucker rod, and thus all parts of the pump may be removed from the well tubing without. disconnecting any sections thereo l The ground joint betneen the beveled or inclined shoulders `13 and 18 and the arrangement of the metallic packing between the upper portion of the pump harreland plunger eilectively prevents leakage of liquid in either direction past the pump and its operating parts. The relatively simple structure of the pump minimizes the initial expensev of installationA and likewise minimizes expense of maintenance and repairs, and, by constructing the pump so that it is lifted from the well tubing by the sucker rod, it is not necessary to provide and maintain additional mechanism for lifting said pump from the well.

Thus it will be seen that I have produced a relatively simple and efficient pump that may be advantageously and economically employed in deep wells and the construction and mounting of said pump being such that it can be readily withdrawn from the well tubing by means of the sucker rod without disturbing any parts of said well tubing.

lt will be readily understood that minor changes in the size, form and construction of the various parts ot my improved pump may be made and substituted for those herein shownand describel without departing 4from the spirit of my invention. the scope of which is set forth in the appended claims.
